SISTOKEN: Treasury Tokenization UX/UI, 2nd Place

SISTOKEN is a system for tokenizing transfers from Brazil's National Treasury, created for the Tesouro Nacional Web3 Hackathon. Our team, "Em busca do tesouro perdido", placed 2nd in the Institutional Partners challenge (Government to Government).

The challenge. Public transfers between government bodies are hard to track. Managers need to see where money goes, what was paid and how it was accounted for, without learning a new technology.

What I did. I designed the experience and interface of the platform using the gov.br design system, so it feels familiar to public servants and follows federal accessibility standards. Key screens include accountability reports, payment reports and program filters, organized in clear tables with status at a glance.

Role. UX/UI designer, from user flows to high fidelity screens.
